Differentiation of bullet type based on the analysis of gunshot residue using inductively coupled plasma mass spectrometry

Porcine tissue samples shot with two different types of bullets, jacketed and nonjacketed, were collected in the fresh state and throughout moderate decomposition. Wound samples were microwave-digested and analyzed using inductively coupled plasma mass spectrometry (ICP-MS) to detect all elements present at measurable levels in gunshot residue (GSR). Elements detected included antimony (Sb), barium (Ba), and lead (Pb), which are considered characteristic of GSR, as well as iron (Fe) and copper (Cu). These five elements were used to differentiate shot tissue and unshot tissue, as well as tissue shot by the two different bullet types, both in the fresh state and throughout moderate decomposition. The concentrations of Cu, Sb, and Pb were able to distinguish the two bullet types in fresh tissue samples at the 95% confidence level. Cu and Pb were able to differentiate the bullet types throughout moderate decomposition at the 99% confidence level.     

Justins v The Queen: assisted suicide, juries and the discretion to prosecute

Juries are often a crucial protection for citizens against unjust or highly controversial laws. The decision whether to proceed with a prosecution rests on the discretionary powers of prosecutors. In cases where the community is deeply divided over right and wrong, it appears that there is, at times, a transference from the public of thwarted law reform aspirations which can create difficult tensions and expectations. This case commentary considers an appeal by Shirley Justins following her conviction for manslaughter by gross criminal negligence as a result of her involvement in the mercy killing of her partner, Mr Graeme Wylie. The morally unsettled nature of the charges brought against her, her own initial plea, the directions given to the jury by the trial judge and even the basis of her appeal resulted in a convoluted and complicated legal case. Spigelman CJ and Johnson J ordered a new trial, Spigelman CJ stating that it was open for a new jury to consider (a) if Mr Wylie lacked capacity; and (b) whether there was criminal involvement by one person in another's death. Simpson J found that further prosecution on the count of manslaughter would amount to an abuse of process and that an acquittal should be entered. This case highlights how fundamentally unsettled are the publicly much debated and persistently contentious issues of euthanasia, assisted suicide, the right of a person to die a dignified death and the way their capacity in that respect should be assessed. It perhaps asks us to reconsider the role of juries and the exercise of discretion by Directors of Public Prosecutions in areas of law where the community and law-makers are deeply and intractably divided.     

Raising household saving: does financial education work?

This article highlights the prevalence and economic outcomes of financial illiteracy among American households, and reviews previous research that examines how improving financial literacy affects household saving. Analysis of the research literature suggests that previous financial literacy efforts have yielded mixed results. Evidence suggests that interventions provided for employees in the workplace have helped increase household saving, but estimates of the magnitude of the impact vary widely. For financial education initiatives targeted to other groups, the evidence is much more ambiguous, suggesting a need for more econometrically rigorous evaluations.     

Predictors of eyewitness identification decisions from video lineups in England: A field study

Eyewitness identification decisions from 1,039 real lineups in England were analysed. Identification procedures have undergone dramatic change in the United Kingdom over recent years. Video lineups are now standard procedure, in which each lineup member is seen sequentially. The whole lineup is seen twice before the witness can make a decision, and the witness can request additional viewings of the lineup. A key aim of this paper was to investigate the association between repeated viewing and eyewitness decisions. Repeated viewing was strongly associated with increased filler identification rates, suggesting that witnesses who requested additional viewings were more willing to guess. In addition, several other factors were associated with lineup outcomes, including the age difference between the suspect and the witness, the type of crime committed, and delay. Overall, the suspect identification rate was 39%, the filler identification rate was 26% and the lineup rejection rate was 35%. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

Fragrance transfer between fabrics for forensic reconstruction applications

Sexual assault is a serious crime that often has low conviction rates. Recent literature has demonstrated that there is potential for fragrances to be valuable in forensic reconstructions where there has been contact between individuals. However, developing appropriate evidence bases for understanding the nature of fragrance transfer in these contexts is needed. This article presents three experiments that address the transfer process of fragrances that have been transferred from a primary piece of fabric onto a secondary piece of fabric, in a manner that could occur during an assault. The three variables studied were the ageing time of the fragrances on the first fabric prior to transfer, the contact time between the two fabrics, and lastly the fabric type (of the primary material and the recipient material). The transfer was evaluated using a validated solid phase micro-extraction gas chromatography–mass spectrometry (SPME GC–MS) method. The findings demonstrated that all three variables had an impact on the transfer of fragrances between clothing fabrics. Generally, lower volatility compounds were transferred and recovered in larger amounts than higher volatility compounds. All fragrance compounds were successfully recovered from a secondary piece of fabric even when the contact time was as short as 10 s, and even when the perfume was aged on the primary fabric for as long as 48 h. The nature of the fragrance transfer also depended on the fabric type, so that a clear discrimination was observed between the fragrance transfer that occurred onto a natural fabric (cotton) and onto a synthetic fabric (polyester).     

Journey history reconstruction from the soils and sediments on footwear: An empirical approach

The value of environmental evidence for reconstructing journey histories has significant potential given the high transferability of sediments and the interaction of footwear with the ground. The importance of empirical evidence bases to underpin the collection, analysis, interpretation and presentation of forensic trace materials is increasingly acknowledged. This paper presents two experimental studies designed to address the transfer and persistence of sediments on the soles of footwear in forensically relevant scenarios, by means of quartz grain surface texture analysis, a technique which has been demonstrated to be able to distinguish between samples of mixed provenance.It was identified that there is a consistent trend of transfer and persistence of sediments from hypothetical pre-, syn- and post-crime event locations across the sole of the shoe, with sediments from ‘older’ locations likely to be retained in small proportions. Furthermore, the arch of the shoe (the area of lowest foot pressure distribution) typically (but not exclusively) retained the highest proportion of grain types from previous locations including the crime scene. A lack of chronological layering of the retained sediments was observed indicating that techniques that can identify the components of mixed provenance samples are important for analysing footwear sediment samples. It was also identified that the type of footwear appeared to have an influence on what particles were retained, with high relief soles that incorporate recessed areas being more likely to retain sediments transferred from ‘older’ locations from the journey history. In addition, the inners of footwear were found to retain sediments from multiple locations from the journey history that are less susceptible to differential loss in comparison to the outer sole. These findings provide important data that can form the basis for the effective collection, analysis and interpretation of sediments recovered from both the outer soles and inners of footwear, building on the findings of previously published studies. These data offer insights that enable inferences to be made about mixed source sediments that are identified on footwear in casework, and provide the beginnings of an empirical basis for assessing the significance of such sediment particles for a specific forensic reconstruction.     

feminism,policy and women's safety during Australia's ‘war on terror’

The main argument in this article is that the Australian government in power from 1996 to November 2007 failed women's domestic security by denying the central policy role of women's organizations in the struggle against domestic violence and by successfully expunging public debate on gender issues in Australian governance, while participating in the ‘war on terror’ to guard national security. In bringing together a discussion about the war on terror and the importance of feminism for women's security, key issues about feminism, race and gender are considered. This article also explores the prevalence of violence against women and the social implications of the lack of leadership in public debate about the gendered nature of violence against women. Under the Australian government led by Prime Minister John Howard that gained power in 1996 and was defeated in 2007, women's organizations lost financial support and women's policy infrastructure was decimated. Violence against women, however, continued to increase, reaffirming women's place in Australian society as insecure and dangerous. After more than 30 years of struggle to maintain domestic violence and sexual assault as serious social policy problems, provide services, support and advocacy for women who are victims of violence and assault, women's organizations are coming to terms with a society where there is a blindness to the role of gender in violence against women.     

Community engagement and public administration: Of silos,overlays and technologies of government

The public policy process in Australia is changing towards a more interactive, collaborative model, where governments seek to develop partnerships with civil society and private sector organisations to manage complex policy challenges. This article discusses research conducted into a project implemented by a Victorian government department that sought to involve stakeholders in addressing natural resource management issues in the agricultural sector. The research revealed that public administration practices associated with the new public management approach impeded the ability of the project to facilitate participation by diverse stakeholders in the decision‐making process. The article challenges the view that the discourse of collaboration and community engagement takes public administration down a constructivist path and suggests that agencies need to become reflexive about the way in which public administration practices are constitutive of the community engagement process if they are to facilitate genuine participation of other stakeholders.
